Great Job, Jeff, lol I new you would get it. that is so freaking awesome. next is yucca on mesquite right lol.
It is real easy too. Yucca on willow,cottonwood, you name it try it out on a bunch of different wood in your area.
Yea cottonwood is a great one to. maple, sycamore, mullberry, willow, hack berry, elm, ceder, white pine,
linden, capolta, birch, These are hard woods so wait on them but hard wood do work just fine too. hickory, oak, walnut, locust hedge apple etc,.
I did the bow drill with cottonwood for the hearth and willow for the spindle had a coal in 11 strokes. so do not wait and think about this stuff just grab some wood carve your spindle and hearth and get at it.
Softer woods are better to start with but once you get it, you owen it. Then start one other types of woods.
When you cut the wood try and make sure it is not rotten
OR
cut it green and then do all your carving, set it aside for a few days to dry and then it should be ready to go. I have said this before I have cut green wood from the cypress tree and in 6 hours of drying time in the sun at 52 degrees and a light breeze spun up a coal. 6 freaking hours after being cut green.
There is a guy on youtube that cut some green willow and then says that he as to wait 3 months for it to dry. That is a crock of crap. in a few days depending on where you live at it could take a few more days but most soft to even med hardness wood will be ready to start spinning up coals with.
For a great fricition fre bearing or socket what ever you want to call it, all you got do is take small piece of steel and drill a little ways into it and then glue it to a piece of wood or leather what ever lol.
that is what I did with this one.
If you want to make your drill hole more rounded then just use a round head bit like a carbide bit.
Again Great job, Jeff.
